[0025] A cast aluminum smelting furnace head described in the present invention is fixedly connected to a motor 2 above a furnace head body 1. During installation, the user turns on the motor 2, and the rotation of the motor 2 drives the long shaft 5 connected below to rotate. The long shaft 5 is located in the through hole 4 of the furnace head body 1. The rotation of the long shaft 5 drives the feeding device 6 fixedly connected to the outer surface to rotate, and the long shaft 5 passes through the interior of the furnace head body 1. When the furnace head body 1 is installed, the rotation of the motor 2 drives the entire long shaft 5 to rotate inside the furnace head body 1. A No. 1 bevel gear 7 is fixedly connected to the top of the long shaft 5. When the long shaft 5 rotates, the No. 1 bevel gear 7 moves along with it, and the No. 2 bevel gear 8 meshing with it also rotates. A No. 1 transmission groove 9 is provided on the side of the No. 2 bevel gear 8 away from the long shaft 5. The side of the No. 2 bevel gear 8 away from the long shaft 5 is fixedly connected to a No. 1 transmission rod 11 and is connected to a No. 1 bearing 10 on the inner wall of the No. 1 transmission groove 9. Rotational connection, when the No. 2 bevel gear 8 rotates, the No. 1 transmission rod 11 rotates accordingly, thereby driving the turbine 12 fixedly connected to the end of the No. 1 transmission rod 11, and the turbine 12 then drives the worm 16 meshing therewith to move. A No. 2 transmission groove 13 is provided inside the furnace head body 1 and below the end of the No. 1 transmission rod 11 away from the long axis 5. A No. 2 transmission rod 15 is fixedly connected below the worm 16 and is rotationally connected to two No. 2 bearings 14 located on the inner wall of the No. 2 transmission groove 13. When the worm 16 moves, it drives the No. 2 transmission rod 15 to rotate, so that the fixing device 17 fixedly connected to the end of the No. 2 transmission rod 15 is fixed to the upper surface of the furnace body 22. When in use, the lifting mechanism 3 rises, the No. 2 bevel gear 8 is disengaged from the No. 1 bevel gear 7, and the motor 2 drives the long axis 5 to rotate, thereby driving the feeding device 6 to work.

[0026] As a specific embodiment of the present invention, the feeding device 6 includes an annular feed pipe 61, a No. 1 feed pipe 62 and a No. 2 feed pipe 63. The outer surface above the annular feed pipe 61 is provided with an annular groove 611. The bottom end of the No. 1 feed pipe 62 is connected to the annular groove 611. The No. 2 feed pipe 63 is multiple and is fixedly connected to the lower end of the annular groove 611 in an array and is located inside the furnace head body 1. The middle end of the long axis 5 is fixedly connected with a scraper plate 18 inside the furnace head body 1. A discharge port 19 is provided inside the furnace head body 1 and below the scraper plate 18. The end of the long axis 5 is fixedly connected to the auger 20 and is located inside the discharge port 19.

[0027] When the user turns on the motor 2 for use, the feeding device 6 on the outer surface of the long axis 5 moves accordingly, and the aluminum liquid enters from the No. 1 feeding pipe 62, and then passes through the annular groove 611 and enters the interior of the furnace head body 1 from the No. 2 feeding pipe 63. In order to prevent the aluminum liquid from overflowing from the annular groove 611, the present invention strictly controls the flow rate of the aluminum liquid per unit time when conveying the aluminum liquid. When the long axis 5 rotates, the No. 2 feeding pipe 63 arranged in an array inside the furnace head body 1 will rotate at a high speed, so that the aluminum liquid in the No. 2 feeding pipe 63 can be accelerated to enter the interior of the furnace head body 1 through the centrifugal force generated by the high-speed rotation. Compared with traditional pipeline transportation, the present invention can accelerate the flow of aluminum liquid through the centrifugal force generated by rotation, and increase the infusion amount of aluminum liquid per unit time. After entering the interior of the body, the aluminum liquid will pass through the auger 20 rotating with the long axis 5 to accelerate the flow rate and flow out from the bottom discharge port 19.

[0028] As a specific implementation of the present invention, the scraper plate 18 is fixedly connected to the long axis 5 in a stepped shape, and a guide groove 21 is opened on the outer surface of the scraper plate 18.

[0029] When the aluminum liquid is rotated at high speed by the No. 2 feed port 63, it will be thrown onto the inner wall of the furnace head body 1 through centrifugal force, so a scraper plate 18 is fixedly connected to the middle section of the long axis 5, which rotates with the long axis 5 and then scrapes off the aluminum liquid remaining on the inner wall. The scraper plate 18 is stepped, which can make part of the aluminum liquid falling on the surface of the scraper plate 18 flow down quickly to prevent deposition on the surface of the scraper plate 18. A guide groove 21 is provided on the outer surface of the scraper plate 18, and the scraped aluminum liquid can pass through the guide groove 21 and flow out faster along with the auger 20.

[0030] As a specific embodiment of the present invention, the fixing device 17 includes a No. 2 transmission rod 15 and a slider 171, the slider 171 is arc-shaped, and the slider 171 is fixedly connected to the lower end of the No. 2 transmission rod 15, and an arc groove 23 is opened on the upper surface of the furnace body 22.

[0031] A slider 171 is fixedly connected to the end of the No. 2 rotating rod 15. The slider 171 is arc-shaped. During installation, the furnace head body 1 is hung above the furnace body 22 and the slider 171 is aligned with the arc groove 23 on the upper surface of the furnace body 22. The motor 2 rotates to drive the No. 1 bevel gear 7 to move, and the No. 2 bevel gear 8 meshing therewith drives the No. 1 transmission rod 11 and the turbine 12 worm 16 and the No. 2 transmission rod 15 to rotate. The No. 2 transmission rod 15 rotates the slider 171 to cooperate with the annular groove on the upper surface of the furnace body 22 to fix the stability of the entire furnace body 22, which is also convenient for installation and disassembly.

[0032] As a specific implementation of the present invention, the lifting mechanism 3 includes a bottom plate 31 and an electric push rod 32 , and the bottom plate 31 is fixedly connected to the furnace head body 1 via the electric push rod 32 .

[0033] After the motor 2 stops, the lifting mechanism 3 is started, the electric push rod 32 pushes the bottom plate 31, and the motor 2 at the upper end of the bottom plate 31 moves upward, driving the first bevel gear 7 and the second bevel gear 8 below to disengage from the meshing state, and the motor 2 drives the long shaft 5 to rotate, thereby driving the feeding device 6 to work.

[0034] As a specific embodiment of the present invention, a lifting lug 24 is fixedly connected to the upper surface of the furnace head body 1 , and a circular hole 25 is opened in the middle of the lifting lug 24 .

[0035] Two lifting ears 24 are fixed on the outer surface of the entire furnace head body 1 , and the middle of the lifting ears 24 is set in the shape of a circular hole 25 for easy positioning and installation.

[0036] Working principle: A cast aluminum smelting furnace head described in the present invention is fixedly connected to a motor 2 above the furnace head body 1. During installation, the user turns on the motor 2, and the rotation of the motor 2 drives the long shaft 5 connected below to rotate. The long shaft 5 is located in the through hole 4 of the furnace head body 1. The rotation of the long shaft 5 drives the feeding device 6 fixedly connected to the outer surface to rotate, and the long shaft 5 runs through the inside of the furnace head body 1. When the furnace head body 1 is installed, the rotation of the motor 2 drives the entire long shaft 5 to rotate inside the furnace head body 1. A No. 1 bevel gear 7 is fixedly connected to the top of the long shaft 5. When the long shaft 5 rotates, the No. 1 bevel gear 7 moves along with it, and the No. 2 bevel gear 8 meshing with it also rotates. A No. 1 transmission groove 9 is provided on the right side of the No. 2 bevel gear 8. The right side of the No. 2 bevel gear 8 is fixedly connected to a No. 1 transmission rod 11 and is rotationally connected to a No. 1 bearing 10 on the inner wall of the No. 1 transmission groove 9. Then, when the No. 2 bevel gear 8 rotates, the No. 1 transmission rod 11 rotates accordingly, thereby driving the turbine 12 fixedly connected to the end of the No. 1 transmission rod 11, and the turbine 12 then drives the worm 16 meshing therewith to move. A No. 2 transmission groove 13 is provided inside the furnace head body 1 and below the end of the No. 1 transmission rod 11 away from the long axis 5. A No. 2 transmission rod 15 is fixedly connected below the worm 16 and is rotatably connected to two No. 2 bearings 14 located on the inner wall of the No. 2 transmission groove 13. When the worm 16 moves, it drives the No. 2 transmission rod 15 to rotate, so that the fixing device 17 fixedly connected to the end of the No. 2 transmission rod 15 is fixed to the upper surface of the furnace body 22. When in use, the lifting mechanism 3 rises, the No. 2 bevel gear 8 is disengaged from the No. 1 bevel gear 7, and the motor 2 drives the long axis 5 to rotate, thereby driving the feeding device 6 to work.

[0037] When the user turns on the motor 2 for use, the feeding device 6 on the outer surface of the long axis 5 moves accordingly, and the aluminum liquid enters from the No. 1 feeding pipe 62, and then passes through the annular groove 611 and the No. 2 feeding pipe 63 into the interior of the furnace head body 1. In order to prevent the aluminum liquid from overflowing from the annular groove 611, the present invention strictly controls the flow rate of the aluminum liquid per unit time when conveying the aluminum liquid. When the long axis 5 rotates, the No. 2 feeding pipe 63 arranged in an array inside the furnace head body 1 will rotate at a high speed, so that the aluminum liquid in the tube can be accelerated to enter the interior of the furnace head body 1 through the centrifugal force generated by the high-speed rotation. Compared with traditional pipeline transportation, the centrifugal force generated by the rotation of the present invention can accelerate the flow of aluminum liquid and increase the infusion amount of aluminum liquid per unit time. After the aluminum liquid enters the interior of the body, it will pass through the auger 20 rotating with the long axis 5 to accelerate the flow rate and flow out from the bottom discharge port 19.

[0038] When the aluminum liquid is rotated at high speed by the No. 2 feed port, it will be thrown onto the inner wall of the furnace head body 1 through centrifugal force, so a scraper plate 18 is fixedly connected to the middle section of the long axis 5, which rotates with the long axis 5 and then scrapes off the aluminum liquid remaining on the inner wall. The scraper plate 18 is stepped, which can make part of the aluminum that falls on the surface of the scraper plate flow down quickly to prevent deposition on the surface of the scraper plate 18. A guide groove 21 is provided on the outer surface of the scraper plate 18, and the scraped aluminum liquid can pass through the guide groove 21 and flow out faster along with the auger 20.

[0039] A slider 171 is fixedly connected to the end of the No. 2 rotating rod. The slider 171 is arc-shaped. During installation, the furnace head body 1 is hung above the furnace body 22 and the slider 171 is aligned with the arc groove 23 on the upper surface of the furnace body 22. The motor 2 rotates to drive the No. 1 bevel gear 7 to move, and the No. 2 bevel gear 8 meshing therewith drives the No. 1 transmission rod 11 and the turbine 12 worm 16 and the No. 2 transmission rod 15 to rotate. The No. 2 transmission rod 15 rotates the slider 171 to cooperate with the arc groove 23 of the furnace body 22, thereby fixing the stability of the entire furnace body 22 and facilitating installation and disassembly.

[0040] After the motor 2 stops, the lifting mechanism 3 is opened, the electric push rod 32 pushes the bottom plate 31, and the motor 2 at the upper end of the bottom plate 31 moves upward, driving the first bevel gear 7 and the second bevel gear 8 below to disengage from the meshing state, and the motor 2 drives the long shaft 5 to rotate, thereby driving the feeding device 6 to work.

[0041] Two lifting ears 24 are fixed on the outer surface of the entire furnace head body 1, and the middle of the fixing frame is set in the shape of a circular hole 25, which is convenient for positioning and installation.

[0042] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
